ROLLIN COLTER.

SPECIFICATION forming part'of Letters Patent No. 407,568, datedJuly 23.1889.

Application filed May 3, 1889. Serial No. 309,531- (No model.)

To all whom, it may concern:

citizen of the United States, and a resident of Canton, county of Stark,State of Ohio, have invented a new and useful Improvement in RollingOolter's, of which the following is a full, clear, and exactdescription, reference being had to the'accompanying drawings, makingpart of this specification.

My invention relates to an improvement in rolling colters for plows, andparticularly to providingimproved means for pivotally securing thecolter-arm, providing for lateral and vertical adjustment of the colter,and means for securing the parts in desired adj ustment.

With these ends in view my invention consists of certain features ofconstruction and combination of parts, as herein after described, andset forth in the claims.

Figure 1 of the accompanying drawings is a view in perspective from therear right of a fragment of a plow-beam and a colter attached thereto,-illustrating my invention; Fig. 1, a fragment of Fig. 1, hereinafterlettered and explained; Fig. 2, a side elevation of supporting plate andarm; Fig. 3, a perspective comprising the supporting-arm and fasteningbolts and keys.

Similar letters of reference indicate corresponding parts in all of thefigures of the drawings.

A represents a fragment of the front portion of a plow-beam severedtransversely under the binding-yoke B.

Plate 0, which forms .an essential feature in the construction of myinvention, is provided with an upper face portion, as a, adapted to restagainst the bottom portion of the beam A, and to secure it thereto sidewings, as b, are provided, having on their under side a countersink c,as shown in Fig. 1, and a perforation c. The yoke B having corresponding perforations, bolts, as d, are passed through the perforation c in thewings I), one on each side of the beam and through the perforations inthe yoke B, and nuts e turned thereon, thus securing the plate 0 to thebeam A.

To provide for vertical and lateral adj ustment of the rolling colter,the lower face portion of the plate 0 is made concave or circularincross-section, as shown at z in Fig. 2,

and is provided with parallel arms f, projected from the body portion ofsaid plate, the inner face g of said 'arms to be circular incrosssection to conform with the circle Z of the body portion 0. For thepurpose of this application I have shown slots, as h, extending aboutcentrally from one end portion to the other, the object of which is toprovide means whereby the depending supporting arm D may be adjustedlaterally or transversely to the line of draft of the plow. The headportion E of the arm D, on its outer upper sur face portion, isconvexed, as shown in Fig. 3, and adapted to the concave portion of theplate 0, as shown in Fig. 2.

a I would not limit myself to the use of the slot h described, as aseries of perforations may be used to accomplish the same purpose, ifpreferred, in which case, however, the removal of the bolts k, by whichthe head E of arm D is secured to the plate for the purpose ofadjustment, would be necessary; but, as shown in Fig. 1, it is onlynecessary to slack the bolts 10 to move the head for either a verticalor lateral adjustment. For the former the head is rocked in the circularface of the plate 0, and for the latter is moved transversely to theline of draft.

The wings m, of the head E extend outwardly from the head, as shown,.inline with the line of draft, and are provided wit-h oblong apertures n,through which bolts, as k, are passed and by which the head is securedin adjustment.

At the front end portion of the colter-arm F is provided a sleeve 19,adapted to embrace the arm D, the rear portion of the arm bifurcated,the prongs q extending rearwardly on eachside of and to the centralportion of the colter G, to which the said colter is pivotally secured,the said sleeve loosely secured to the arm D by inserting the key 4 inthe perforation 8.

It will be evident that to adjust the colter either vertically orlaterally it will only be necessary to slack the nuton the bolts lawhenthe arm F may be raised or lowered by rocking the head portion E of thearm D in the convex portion of the plate 0, and for lateral adjustmentthe head E may be moved transversely to the line of draft and secured indesired adjustment by tightening the aforesaid bolts. It will be furthernoticed that the space occupied under the beams by the dependingportions is unusually small and not projecting down in front of theeolter, thereby interfering with the operation of the colter as well asthe plow.

Having thus fully described the nature and object of my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. The combination, with a plow-beam A, of the plate 0, having its lowerface portion circular in cross-section, arms f and 1), bolts (Z, andyoke B,whereby the plate 0 is secured to the beam, substantially asdescribed, and for the purpose set forth.

2. The combination, with the beam A, the plate 0, having its lower faceportion circular in cross-section, an arm D, having a convex headportion E, having perforations at, and means for securing said head indesired adjustment with the plate 0, substantially as described, and forthe purpose set forth.

3. In combination with the beam A, the plate 0, having side projectingarms f, provided with slots h, the under surface of said plate beingcircular in cross-section, a dcpending arm, as D,having a convex headportion, as E, adapted to rock in the circular face of the plate 0.

4. In combination with the beam A, plate 0, having a concaved lowerface. portion, parallel arms f, circular in cross-section, slots h, armD, having a convex head E, adapted to rock in said concave in line withthe draft and to move laterally, a colter G, arm F, having a sleeveportion, as p, loosely secured about an arm, as D, and means forsecuring said arm in desired adjustment with the plate 0, substantiallyas described, and for the purpose set forth.

5. In combination, the colter G, colter-arm F, supporting-arm D, havinga convex head E, adapted for lateral adjustment, a supporting-plate, asC, having a concaved under portion and parallel arms circular incross-section, and means for securing said head in desired lateraladjustment on said plate or arms, substantially as described, and forthe purpose set forth.

In testimony whereof I have hereunto set my hand this 26th day of April,A. D. 1889.
